There are about 10004 clinical studies being (or have been) conducted in Brazil. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Among the causes associated with infection of hospitalized patients, surgical site infection is a complication that is potentially associated with any type of surgical procedure, it also represents an expressive burden in terms of morbidity and mortality, as well as additional costs for health care systems around the world. It is regarded that the efficiency of the pre, per, and postoperative skin preparation depends on both the adopted antiseptic and the application method, with Chlorhexidine currently being the most used drug in such preparation. However, the manner, timing, or timing of cutaneous antisepsis action is unclear. Objective: Comparing antisepsis techniques using chlorhexidine-based soap associated with ethyl alcohol and alcoholic chlorhexidine versus chlorhexidine-based soap associated with alcoholic chlorhexidine, in surgical orthopedic procedures.
Preclinical models of urogenital carcinoma have been emerging as a way to pre-determine drug resistance before therapy is targeted. The implantation of tumor specimens in the chorioallantoic membrane (CAM) of the chicken embryo results in a high-efficiency graft, thus allowing large-scale studies of "tumor avatar". The aim of the study is to develop a tumor culture platform for treatment evaluation. Biopsies will be collected from primary tumors of patients and grafted onto the chorioallantoic membrane of chicken embryos. After tumor implantation at the CAM, tumor growth will be accompanied by imaging that will quantify tumor vascularization, tumor volume, and tumor blood flow. Following tumor growth, "avatars" will be divided into different treatments. Using the "tumor avatar" model together with patient tumors, the investigators will be able to observe the individualized tumor response for each patient in a treatment context, as well as determine the potential drug to be used in each case. These results may support a phenotype-based reading within 7-10 days.
The objective of this study is to evaluate the effects of continuous positive airway pressure and nasal intermittent positive pressure ventilation on breathing pattern variables of very low birth weight neonates immediately after extubation.
The positive effect of physical training in patients with heart failure (HF) has been increasingly established. However, the presence of atrial fibrillation (AF), mainly in its permanent form, makes the clinical condition of the patients more compromised.
Study AG348-C-006 evaluated the efficacy and safety of orally administered AG-348 as compared with placebo in participants with pyruvate kinase (PK) deficiency, who were not regularly receiving blood transfusions. Participants were randomized 1:1 to receive either AG-348 or a matching placebo.
The type II diabetes is characterized by high levels of blood glucose followed by excessive insulin release so that the target cells become less sensitive and develop insulin resistance, maintaining hyperglycemic levels. The Whole body vibration session may improve the glucose metabolism in diabetic patients by reducing the peripheral blood sugar. Ten healthy elderly women and eight diabetic elderly women were allocated into two groups, and have made an acute whole body session.
This study evaluates the hypoalgesic effect of global and specific cervical joint manipulation in healthy individuals. At first the participants received one of the interventions and after 48 hours, the other.
Studies in the literature have shown reduced effectiveness of influenza A (H3N2) virus vaccine (20-40%) when compared to A (H1N1) and influenza B. This reduction in efficacy may partly result of the need to propagate A (H3N2) virus into egg components for the preparation of the vaccine. Other factors that may also contribute to the reduction of efficacy against A (H3N2) viruses include the high level of genetic diversity and the rate of rapid evolution of this particular virus subtype and the modification of the immune response to the vaccine secondary of prior infection or vaccination. Vaccine efficacy studies are required to verify the immunogenicity of the H3N2 influenza vaccine in immunosuppressed patients with rheumatologic disease. In addition, it is relevant to evaluate the safety of the vaccine in this population as well as the possibility of reactivation of the rheumatologic disease itself. The objectives of this study are to evaluate the immunogenicity of the H3N2 component of the inactivated and fragmented influenza vaccine in patients with two systemic autoimmune rheumatic diseases (Systemic Lupus Erythematosus - Adult and Juvenile, Primary Sjögren's Syndrome).
Vaccine pain control is one of the actions suggested to support the delivery of vaccines that are on a vaccine schedule, since pain and anxiety associated with vaccines are among the main reasons why children and their parents fail to do them properly. Thus, it is very important to investigate which interventions can bring greater benefit in the control of pain.This is a randomized clinical trial aiming to assess the impact of video distraction and vibration device on pain during the vaccination of children between one and three years.
This trial aims to develop an electronic learning (eLearning) program and mobile tool for Spanish and Portuguese speaking cancer care providers to use in tobacco counseling of their patients. This study may provide information for the design and implementation of tobacco cessation training programs directed to this group of professionals in low- and middle-income countries for the Latin American region.
